En fråga! =)

Tror det är 2,8 eller om det är 2,85 ns minnen

Nowadays, Samsung does not follow suit with other memory makers and distinguish the nanosecond rating of RAM chips with like a -7.5 (133 MHz), but rather, they use funky alpha-numeric codes. Our Radeon 9700 sample boasted 128MB of Samsung K4D26323RA-GC2A DDR SDRAM. According to Samsung, -GC2A corresponds to a maximum operating frequency of 350 MHz (700 MHz DDR). Doing the math, this memory has a 2.86-nanosecond specification.

2,86 ns var det till och med.
